I This invention comprises a ineansf r exclud ng drafts'from under doors,- a' 'id t consists of a, horizontal member, the lower side of which is fitted with ,afeltor frubberflor other suitable surface to form a pad, which I engages the floor whenfthejidoorjis closed.

The horizontal member is hinged to the 1 lower part of the door by means of one or two hor zontally arranged hingeswhich permitthe horizontal" member to ib'elturned on I "a horizontal axis away from the door, so as to lift the engaging face off the floor, as the door lsopeneda, Thishin ging eifect'is secured by means vof'a'doublediinged"fitting applied to the door jainb atthehaiiging side and to the end of, the horizontal Vniember, the said double-hinged fitting comprising an angular central portion, and twojhinged plates, one for attachment to the door jamb and the other for attachment to' the horizontal'meinber, in such a way that the angular central plate maybe connected to the door jamb and to the end oftthe horizontal member with the knuckles of the hinges be ing held approximately at similar angles to the floor, the apex of the axis ofthe hinges approximately intersecting the axis of the hinges which support the door, to which axis both knuckle joints converge and their axes intersect at the same point. The hinge plate which is attached to the doorjamb at the hanging side, is attached in a plane parallel with the plane of the door surface, but the axis of the knuckle joint of the hinge plate which is attached to the horizontal member is contained in a plane oblique to the plane containing the surface of the door, such plane diverging outwards and in a down ward direction. Y In order that the invention may be clearly I understood, reference is made to the accom- I panying drawings, in which Figure 1 illustrates the draft exclude attached to the lower edge of the door;

Figure 2 is an enlarged view showing the two hinged plates, and'the angular central plate all in the same plane, Y

Figures 3, 4: and 5 are respectively front elevation, sectional plan, and sectional end view, showingthe horizontal memberand the double hinged fitting in position when the door is closed, and

Figures 6 and 7 are respectively sectional plan and sectional elevation showing the same parts ,open. j

The horizontal member, which "is marked horizontal member for supporting the outer end of such horizontal member A, while perm tting it to be turned on a longitudinal axis in order to lift the horizontal member away from the ground asthe door is opened.

C, is the angular central plate of the double hinged fitting; D is the hingeplate for attachment to the door jamb; Efis the hinge plate forattachment to the end of thev horizontal member.v These hinge plates D "and 'E are hinged 'at the knuckle joints D and E to theangular centralplate C, 3 As :wi'll be seen best at Figure 4, the axis of the knuckle joint'E' inclines outwards in a downward direction. F is the surface attached to the horizontal member A, which,

in the drawings, illustrated as rubber pipmg surrounded with fabric which is attached at Fto the inner face of the horizontal member A. G is an additional hinge for connecting the horizontal memberA to the door at an intermediate position. This hinge G permits the horizontal member A, after being fitted to the door by the hinge B and the double-hinged fitting, to be bent downwards in order to fill in any irregularity in the floor. hen the door is opened, the opening angle is communicated to the horizontal member A by the movement of the door,

in position when" the door is in thedrawings, is shown constructed of and the double-hinged fitting divides this movement between the knuckle joint D and the knuckle joint E. If the hinge plates D and E were in the same plane, these axes would be on'a'dead centre and would result in the breakage of the doublehinged fitting owing to no lead being given for the double-hinged fitting-t0 give angular movement in one direction or the other. It is to overcome this dead point that the axis of the hinge E is inclined to the plane containing the surface of the door.

The effect of the opening of the door and I the consequent angular movementimposed on the double-hinged fitting, is to turn the horizontal member outwards from the door,

and thus lift the lower contact edge away ill) from the floor. The extreme limit of this movement illustrated at Figure 7.

Although the double-hinged fitting has i been illustrated with the hinges converging, each at an angle of 45 relatively to the floor, this angle can be varied within certain limits, providing the axes of the knuckle joints of the hinges maintain similar angles.

hat we claim as our invention and desire to secure by Letters Patent is 1. In association with a draft excluder for doors in which a horizontal member is hinged to the lower portion of the door and required to be automatically angulnrly turnel'l on a horizontal axis when the door is opened, the combination of a doublehinged fitting, comprising a hinged plate for attachment to the door jamb, a hinged plate for attachment to the horizontal member, and an angle plate to which both hinges are jointed at equal angles, one of such hinge joints being inclined to the plane containing the face of the door, whereby angular adjustment is automatically given to the horizontal member by the opening of the door.

Q. In association with a draft excluder for doors in which a horizontal member is hinged to the lower portion of the door and is required to be auton'iatically turned on its hinges when the door is o ened, the combination of a double-hinged fitting, comprising a hinged late for attachment to the door j amb, a hinged late for attachment to the inner end of the iorizontal member and an angle plate to which both hinges are jointed at right angles to each other, one oi such hinge joints being inclined to the plane containing the face of the door, whereby angular adjustment is automatically given to the horizontal member by the opening oi: the door.

3. In association with a draft exoludcr for doors in which a horizontal member is hinged at its outer end to the lower portion of the door, and a hin e located about centrally between the horizontal member and the door, and is required to be automatically turned on its hinges when the door is opened, the combination of a double hinged fitting, comprising a hinged plate for attachment to the door jamb, a hinged late for attachment to the inner end of the iorizontal member, and an angle plate to which both hinges are 'ointed at right angles to each other, one 0 such hinge joints being inclined to the plane containing the face of the door, whereby angular adjustment is automatically given to the horizontalmember by the opening of the door.

In witness whereof we have hereunto set our hands.
